I should know better by now, but just wasted another half hour debugging a
mysterious NewPM bug, which came down to a missing -aa-pipeline=default in the
opt invocation. I've seen others fall in the same trap as well. If someone uses
a default optimization pipeline, it stands to reason that they also want to use
a default AA pipeline.
